Remove authors from Cargo.toml

[stefnotch]

The Dioxus CLI generates a Cargo.toml with an authors field. However, that field is deprecated. If one uses a toml linter, this even results in a warning.

So this line should be removed in all templates.

dioxus-template/Web/Cargo.toml

Line 4 in fdaeaae

authors = ["{{authors}}"]
